Title: Ferromagnetic tunnel joint
Inventor: OIKE TARO
IPC: H01L43/08
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To obtain a high MR changing factor with a good reproducibility by setting the barrier potential made by an insulation layer to the range of a specific eV in the ferromagnetic tunnel joint in which a first ferromagnetic layer, an insulation layer and a second ferromagnetic layer are successively laminated. SOLUTION: In the ferromagnetic tunnel joint, a first ferromagnetic layer 1, an insulation layer 3 and a second ferromagnetic layer 2 are successively laminated on an appropriate insulation supporting base plate 4. In this construction, the barrier potential made by the layer 3 is set in the range of 0.5 to 3eV. This potential is due to the fact that if the barrier potential exceeds 3eV, no high MR changing factor is obtained and it is estimated that no tunnel current flows. On the other hand, if the barrier potential becomes less than 0.5eV, not expected high MR changing factor is obtained. Thus, if the barrier potential is set within the range of 0.5 to 3eV, a stable and antiferromagnetic coupling is produced through the layer 3 between the layers 1 and 2.

Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal device construction having a new structure without generating display unevenness and malfunctions in a liquid crystal device caused by uneven distribution of liquid crystal toward a specific region in driving the liquid crystal device. SOLUTION: A part of a sealant 3 in the vicinity of a region A is formed as a thinly dressed part 3a which is made thinner than the other parts anticipating an increase of cell thickness in the region A. The cell thickness in the region A is made slightly small because the thinly dressed part 3a is formed thinner than thickness of the other parts of the sealant 3. Thereby as the cell thickness in the region A is increased, due to uneven distribution of liquid crystal 4 toward a flowing direction F of liquid crystal in driving the liquid crystal device, variation in the cell thickness of a liquid crystal panel decreases, a difference of cell thickness between the region A and the other parts diminishes and generation of display unevenness, malfunctions or the like is suppressed.

Filed: 1990-09-19
Abstract: PURPOSE:To control an optical head actuator without providing a particular detector by detecting displacement of an objective lens and driving the optical head actuator based on this displacement signal in order to diminish the displacement of a light spot. CONSTITUTION:When the light spot 11 exists in an area where a guide groove 10 is not formed on an information recording medium 1, an output of a differential amplifier 4 shows mainly displacement of a light beam by a fine movement adjustment means 6, and by sampling and holding a differential signal as of an output from a photodetector 3, the displacement of the light beam by the fine movement adjusting means 6 can be detected. However, since a high frequency component of the displacement of the light beam by the fine movement adjusting means 6 cannot be detected, the displacement of the light beam by the fine movement adjusting means 6 is estimated in a sufficiently high frequency area as against a natural frequency f0 of an input signal, and the estimated displacement of the light beam by the fine movement adjusting means 6 is inputted to a coarse movement adjusting means 9, so that the coarse movement adjusting means 9 is controlled so as to always diminish the displacement of the light beam. By this method, the optical head actuator is controlled without providing a particular sensor.
